## Motivation

[Rube-Goldmark Machine]: https://en.wikipedia.org/wiki/Rube_Goldberg_machine
|
||||
Fastfetch, as its name probably hinted, is a very fast fetch tool written in C.
|
||||
However, I am not interested in _any_ of its additional features, and I'm not
|
||||
interested in its configuration options. Sure I can _configure_ it when I
|
||||
dislike the defaults, but how often would I really change the configuration...
|
||||
|
||||
Fastfetch, as its name _probably_ already hinted, is a very fast fetch tool
|
||||
written in C. I used to use Fastfetch on my systems, but I eventually came to
|
||||
the realization that I am _not interested in any of its additional features_. I
|
||||
don't use Sixel, I don't change my configuration more than maybe once a year and
|
||||
I don't even display most of the fields that it does. Sure the configurability
|
||||
is nice and I can configure the defaults that I do not like but how often do I
|
||||
really do that?
|
||||
Microfetch is my response to this problem. It is an _even faster_ fetch tool
|
||||
that I would've written in Bash and put in my `~/.bashrc` but is _actually_
|
||||
incredibly fast because it opts out of all the customization options provided by
|
||||
tools such as Fastfetch. Ultimately, it's a small, opinionated binary with a
|
||||
nice size that doesn't bother me, and incredible speed. Customization? No thank
|
||||
you. I cannot re-iterate it enough, Microfetch is _annoyingly fast_.
|
||||
|
||||
Since I already enjoy programming challenges, and don't use a fetch program that
|
||||
often, I eventually came to try and answer the question _how fast can I make my
|
||||
fetch script?_ It is an _even faster_ fetch tool that I would've written in Bash
|
||||
and put in my `~/.bashrc` but is _actually_ incredibly fast because it opts out
|
||||
of all the customization options provided by tools such as Fastfetch. Since
|
||||
Fetch scripts are kind of a coming-of-age ritual for most Linux users, I've
|
||||
decided to use it on my system. You also might be interested if you like the
|
||||
defaults and like speed.
|
||||
The project is written in Rust, which comes at the cost of "bloated" dependency
|
||||
trees and the increased build times, but we make an extended effort to keep the
|
||||
dependencies minimal and build times managable. The latter is also very easily
|
||||
mitigated with Nix's binary cache systems. Since Microfetch is already in
|
||||
Nixpkgs, you are recommended to use it to utilize the binary cache properly. The
|
||||
usage of Rust _is_ nice, however, since it provides us with incredible tooling
|
||||
and a very powerful language that allows for Microfetch to be as fast as
|
||||
possible. Sure C could've been used here as well, but do you think I hate
|
||||
myself?

Ultimately, it's a small, opinionated binary with a nice size that doesn't

|
||||
re-iterate it enough, Microfetch is _annoyingly fast_. It does not, however,
|
||||
solve a technical problem. The "problem" Microfetch solves is entirely
|
||||
self-imposed. On the matter of _size_, the project is written in Rust, which

should have seen this coming. Is it faster? Yes.

### Why?
|

|
||||
Customization, of most kinds, are expensive: I could try reading environment
|
||||
variables, parse command-line arguments or read a configuration file to allow
|
||||
configuring various fields but those inflate execution time and the resource
|
||||
consumption by a lot. Since Microfetch is closer to a code golf challenge than a
|
||||
program that attempts to fill a gap, I have elected not to make this trade.

To be fair, you _can_ customize Microfetch by, well, patching it. It is
|
||||
certainly not the easiest way of doing so but if you are planning to change
|
||||
something in Microfetch, patching is the best way to go. It will also the only
|
||||
way that does not compromise on speed, unless you patch in bad code. Various
|
||||
users have adapted Microfetch to their distribution by patching the
|
||||
[main module] and inserting the logo of their choice. This is also the best way
|
||||
to go if you plan to make small changes. If your changes are not small, you

might want to look for a program that is designed to be customizable; Microfetch

is built for maximum performance.

A Nix flake is provided. `nix develop` to get started. Direnv users may simply

run `direnv allow` to get started.
|
||||
|
||||
Non-Nix user will need `cargo`, `clang` and `mold` installed on their system to
|
||||
build Microfetch. As Mold seems to yield _slightly_ better results than the
|
||||
default linker, it has been set as the default in `.cargo/config.toml` for
|
||||
x86-64 Linux. You may override those defaults using the `RUSTFLAGS` environment
|
||||
variable. For example:
|
||||
|
||||
```sh
|
||||
# Use ld instead of Mold
|
||||
$ RUSTFLAGS="-C linker=/path/to/ld.lld" cargo build
|
||||
```
|
||||
Non-nix users will need `cargo` and `gcc` installed on their system, see
|
||||
`Cargo.toml` for available release profiles.
